Define architecture for the frida agent

[bernhste]

Currently, some code used in the iOS and Android agent is duplicated.

In this issue, we want to extract the code into a shared library and refactor it to TypeScript.

Initial suggestion for the components:

1. Bootstrap
2. Hook File Validator
3. Hook Lookup
4. Decoder Lookup
5. Decoder
6. Hooking
7. Event Sender
